Sill slope? Sealant tape?
How much slope is recommended for window sills? The house isn’t in an coastal or otherwise very exposed location, but isn’t in an arid or especially sheltered place either.
I’m planning on using beveled siding, placed on a flat plywood window buck, to help move water away from the opening; the exterior face of the window frame will be set about 4 – 5″ back from the outside of the exterior sheathing. I’m trying to figure out how much extra room (vertically) to include in the rough opening.
Has anyone had real trouble using sealant tape (Hannoband or Tremco, for example)? The window install will likely be during cool weather, hopefully slowing expansion down a little.
